Abstract

An extrusion die (1) for the casting of liquid metals, in particular of liquid steel materials, has a heat flow density which is distributed non-homogenously over the die face. A homogenizing of the heat flow density can be obtained if the spacing between the hot side and the cooling duct base (= thickness (6) of the die wide side plate (2)) in the new state as a typical normal thickness (100%) is reduced by at least 20% to 80%, and a further reduction, obtained by means of reworking processes, of the thickness (6) which is initially reduced to 80% is restricted to 5 mm final thickness (6a) by means of a final reworking process.

Description

Stranggießkokille für flüssige Metalle, insbesondere für flüssige Stahlwerkstoffe Continuous casting mold for liquid metals, in particular for liquid steel materials
Die Erfindung betrifft eine Stranggießkokille für flüssige Metalle, insbesondere für flüssige Stahlwerkstoffe, mit für die Zu- und Ableitung von Kühlmittel von Wasserkästen umgebenen, den Gießquerschnitt mit parallelem und / oder gewölbtem Verlauf begrenzenden Kokillenbreitseitenplatten und Kokillenschmal- seitenplatten aus Kupferwerkstoffen, an deren Kaltseite eine Vielzahl von Kühlmittelkanälen angeordnet ist, die im Gießspiegelbereich unter Verminderung der Dicke der jeweiligen Kokillenbreitseitenplatte einen minimalen Kühlmittel-Kanalquerschnitt aufweisen.The invention relates to a continuous casting mold for liquid metals, in particular for liquid steel materials, with surrounding for the supply and discharge of coolant from water tanks, the Gießquerschnitt parallel and / or curved course limiting Kokillenbreitseitenplatten and Kokillenschmal- side plates of copper materials, at the cold side of a variety is arranged by coolant channels, which have a minimum coolant channel cross-section in the Gießspiegelbereich while reducing the thickness of the respective Kokillenbreitseitenplatte.
Betriebsmessungen an Dünnstrang-Anlagen haben gezeigt, dass die Wärme- belastung der Stranggießkokille sehr ungleichmäßig über die Kokillenfläche verteilt ist. Besonders stark belastet ist der Bereich bis ca. 70 mm unterhalb des Gießspiegels. Die an dieser Stelle gemessenen Wärmestromdichten sind um ein Mehrfaches größer als die mittlere Wärmestromdichte gemessen über die gesamte Kokille. Entlang des Gießspiegels in Breitenrichtung ist die Wärme- stromdichte ebenfalls nicht homogen verteilt. In den äußeren Bereichen der Kokillenbreitseitenplatten werden mehrfach höhere Werte als in der Mitte erreicht, was auf die mittige Anordnung eines Tauchrohrs zurückzuführen ist.Operating measurements on thin-strand plants have shown that the heat load of the continuous casting mold is distributed very unevenly over the mold area. The area is particularly heavily loaded up to approx. 70 mm below the casting level. The measured at this point heat flux densities are many times greater than the average heat flux measured across the entire mold. The heat flow density is also not distributed homogeneously along the width direction of the pouring mirror. In the outer areas of Kokillenbreitseitenplatten multiply higher values than in the middle are achieved, which is due to the central arrangement of a dip tube.
Entsprechend dieser sehr ungleichmäßigen Verteilung der Wärmestromdichte ist auch die Temperatur der Kokillenoberfläche auf der Heißseite, die sich in Kontakt mit dem flüssigen Stahl bzw. der erstarrenden Strangschale befindet, erheblich unterschiedlich. Neben den nicht auszuschließenden negativen Folgen für die gegossenen Stränge (bspw. Brammenquerschnitte oder Dünnstrangquerschnitte) führen die örtlich höheren Oberflächentemperaturen auf der Kokillenheißseite auch zu einem höheren Verschleiß in diesen Bereichen, der sich in lokalen Verwerfungen oder in Rissbildung äußern kann. Sobald der aufIn accordance with this very uneven distribution of the heat flow density, the temperature of the mold surface on the hot side, which is in contact with the liquid steel or the solidifying strand shell, is also considerably different. In addition to the negative consequences that can not be excluded for the cast strands (eg slab cross sections or thin strand cross sections), the locally higher surface temperatures on the hot side of the mold also lead to higher wear in these areas, which can manifest itself in local distortions or in cracking. As soon as the on
BESTATIGUNGSKOPIE der Kokillenheißseite eintretende Verschleiß ein gewisses Maß übersteigt, muss die gesamte Kokillenplatten-Oberfläche einschließlich der weniger beanspruchten oder noch brauchbaren Flächen überarbeitet werden, was nur durch Abfräsen oder ein anderes spangebendes Verfahren erfolgen kann.BESTATIGUNGSKOPIE If the wear occurring on the hot side of the mold exceeds a certain level, the entire surface of the mold plate including the less stressed or usable surfaces must be reworked, which can be done only by milling or another cutting process.
Die eingangs bezeichnete Stranggießkokille ist aus der DE 102 26 214 A1 bekannt. Die dortigen aus Kupferwerkstoff bestehenden kassettenartigen Einsätze liegen auf Stahl-Einsatzplatten auf und können ausgetauscht werden. Dabei ist die Dicke der Kupferplatten zwischen dem Kühlmittel und der Kupferplatten- Heißseite über die Breite und / oder über die Höhe der Kokille unterschiedlich. Der Kühlmittel-Kanal-querschnitt ist in der Höhe im Gießspiegelbereich als Minimal-Dicke ausgeführt und in den unteren Bereichen ist der Kühlmittel- Kanalquerschnitt stets größer, wobei auch der untere Bereich der Dicke der Kupferplatte stets größer ausgeführt ist. Alle diese Maßnahmen können den vorstehend beschriebenen Verschleiß der Kupferplatten nach einer Anzahl von Abgüssen nicht verhindern.The initially described continuous casting mold is known from DE 102 26 214 A1. The existing there from copper material cassette-like inserts rest on steel insert plates and can be replaced. The thickness of the copper plates between the coolant and the copper plate hot side over the width and / or over the height of the mold is different. The coolant channel cross-section is designed as a minimum thickness in height in Gießspiegelbereich and in the lower regions of the coolant channel cross-section is always larger, and the lower portion of the thickness of the copper plate is always made larger. All these measures can not prevent the above-described wear of the copper plates after a number of casts.
Der Erfindung liegt die Aufgabe zugrunde, unterschiedliche Wärmebelastungen der Stranggießkokille innerhalb der Kokillenbreitseitenplatte zu reduzieren und dadurch den Verschleiß zu mindern.The invention has for its object to reduce different heat loads of the continuous casting mold within the Kokillenbreitseitenplatte and thereby reduce wear.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Abstand zwischen der Heißseite und dem Kühlmittelkanal-Grund der Kokillenbreitseitenplatte (= Dicke der Kokillenbreitseitenplatte (2)) im Neuzustand als übliche Normaldicke (100%) um zumindest 20% auf 80% reduziert ist und eine durch Nacharbeitungen eintretende weitere Reduzierung der anfangs auf 80% verminderten Dicke bis auf ca. 5 mm Enddicke durch eine letzte Nacharbeitung beschränkt ist. Dadurch werden die Oberflächentemperaturen der Kokillenheißseite in thermisch besonders hoch belasteten Bereichen reduziert und dadurch wird sowohl die mechanische Belastung der Strangschale verringert als auch die Standzeit der Stranggießkokille verbessert. Dieser positive Effekt einer merklichen Reduzierung der Kokillenbreitseitenplatten- Oberflächentemperaturen stellt sich ein, wenn der Abstand zwischen den Kühlkanälen und der Oberfläche im Neuzustand der Kokille um mindestens 20% reduziert wird. Beim bisherigen Neuzustand kann von 20 - ca. 40 mm Plattendicke ausgegangen werden, je nachdem wie für die betreffende Gießstrangdicke die Breitseitenkokillenplatte angesetzt wird. Es wird demzufolge von den bisher eingesetzten Dickenwerten der Breitseitenkokillenplatten ausgegangen. Dies entspricht bei den derzeitigen, vorausgesetzten Verhältnissen einer Verringerung des Abstandes um 5 mm von der Neudicke aus, die somit verkleinert wird. Am Ende soll der Abstand während des gesamten Betriebs aus Sicherheitsgründen nicht geringer werden als 5 mm.The object is achieved according to the invention that the distance between the hot side and the coolant channel base of Kokillenbreitseitenplatte (= thickness of Kokillenbreitseitenplatte (2)) in new condition than normal thickness (100%) is reduced by at least 20% to 80% and a By reworking further reduction of the initially reduced to 80% thickness is limited to about 5 mm final thickness by a final reworking. As a result, the surface temperatures of the Kokillenheißseite be reduced in thermally highly stressed areas and thereby both the mechanical stress on the strand shell is reduced and the service life of the continuous casting mold improved. This positive effect of a noticeable reduction in chill broadside plate Surface temperatures are reached when the distance between the cooling channels and the surface when the mold is new is reduced by at least 20%. In the previous new condition can be assumed from 20 - about 40 mm plate thickness, depending on how for the relevant Gießstrangdicke the Breitseitenenkokillenplatte is recognized. It is therefore assumed that the previously used thickness values of Breitseitenenkokilleplatten. This corresponds to a reduction of the distance of 5 mm from the new thickness, which is thus reduced, at the present assumed conditions. At the end of the distance during the entire operation for safety reasons should not be less than 5 mm.
Als Beispiel sei genannt: Bei konventionellen Kokillenplatten für Dünnbrammenanlagen mit konstanter Dicke beträgt die Dicke im Neuzustand üblicherweise 25 mm. Dieser Wert wird jetzt zumindest um 5 mm (20%) auf 20 mm reduziert.As an example may be mentioned: In conventional mold plates for thin slab plants with a constant thickness, the thickness is usually 25 mm when new. This value is now reduced by at least 5 mm (20%) to 20 mm.
Weitere Merkmale sind, dass der Kühlmittelkanal-Querschnitt im Gießspiegelbereich verhältnisgleich zur Reduzierung der Dicke der Kokillenbreitseitenplatte vermindert ist.Further features are that the coolant channel cross section in the Gießspiegelbereich is reduced proportionally to reduce the thickness of Kokillenbreitseitenplatte.
Um den Strömungswiderstand und damit den Druckverlust in diesem Bereich nicht zu großen werden zu lassen, ist nach einem anderen Merkmale der Kühlmittelkanal-Querschnitt nicht mehr als 80% des Neuzustandes des Anfangs- Kühlmittelkanal-Querschnitts verringert.In order not to let the flow resistance and thus the pressure loss in this area become too large, according to another feature, the coolant channel cross section is not reduced more than 80% of the new state of the initial coolant channel cross section.
Eine andere Ausgestaltung sieht vor, dass sowohl die Verringerung der Dicke der Kokillenbreitseitenplatte als auch die Reduzierung des Kühlmittelkanal- Querschnitts in Abhängigkeit einer ungleichen Position des jeweiligen Kühlmittelkanals in Breitenrichtung vorgenommen sind.Another embodiment provides that both the reduction of the thickness of Kokillenbreitseitenplatte and the reduction of the Kühlmittelkanal- cross section are made in dependence on an unequal position of the respective coolant channel in the width direction.
Weiterhin wird vorgeschlagen, dass die Kokillenbreitseitenplatten (2) zwischen 5 und 10 mm bis maximal 15 mm in 3-10 Nacharbeitungen in der Dicke (6) vermindert ist, wobei eine einzelne Nacharbeitung aus einer Kupferwerkstoff- Abtragung von 0,3 bis 1 ,5 mm, maximal 3 mm besteht.Furthermore, it is proposed that the chill broad side plates (2) between 5 and 10 mm to a maximum of 15 mm in 3-10 reworks in thickness (6) is reduced, with a single reworking consists of a copper material removal of 0.3 to 1, 5 mm, a maximum of 3 mm.
Die weitere Ausgestaltung sieht vor, dass der Kühlmittelkanal-Querschnitt im Gießspiegelbereich und bis zum Kokillenausgang mittels jeweils eines auf der Kaltseite befestigten Füllstücks aus normaltemperaturbeständigem Werkstoff gebildet ist.The further embodiment provides that the coolant channel cross-section is formed in the Gießspiegelbereich and to Kokillenausgang by means of each one fixed to the cold side filler of normal temperature resistant material.
Dabei ist noch von Vorteil, dass das Füllstück zur Reduzierung des Kühlmittelkanal-Querschnitts justierbar ist.It is also advantageous that the filler for reducing the coolant channel cross-section is adjustable.
Eine alternative Ausbildung des Gießraums sieht vor, dass zumindest die Kokil- lenbreitseitenplatten als Kassettenplatten ausgebildet sind, die auf der Kaltseite ausbaufähig auf gekühlten Adapterplatten anliegen.An alternative embodiment of the pouring space provides that at least the Kokil lenbreitseitenplatten are formed as cassette plates, which abut on the cold side on cooled adapter plates.
Eine darauf aufbauende Weiterbildung ergibt sich dadurch, dass auf der Adapterplatte zur Bildung des minimalen Kühlmittelkanal-Querschnitts ein separater Verdrängerkörper vorgesehen ist.A further development is based on the fact that a separate displacement body is provided on the adapter plate to form the minimum coolant channel cross-section.
Der Verdrängerkörper kann mit unterschiedlichen Profilen ausgebildet , bevor- ratet und austauschbar befestigt sein.The displacer can be formed with different profiles, provided and exchangeably secured.

Die Stranggießkokille 1 (Fig. 1 ) ist durch zwei den Gießquerschnitt 1 b begrenzenden Kokillenbreitseitenplatten 2 und durch an den Enden befindlichen Kokil- lenschmalseitenplatten 3 gebildet, wobei ein Kühlmittel 1a (wie bspw. Wasser) unter Druck durch Kühlmittelkanäle 4 (Fig. 2 bis 4) geführt wird. Wie ersichtlich, werden durch den Einfluß eines Tauchrohrs 12 im Gießspiegelbereich 5 unter- schiedliche Bereiche 5a und 5b der Wärmestromdichte gebildet. Die Wärmestromdichte in den Bereichen 5a ist höher als in dem Bereich 5b. Außerdem entstehen durch die aus dem Tauchrohr 12 austretenden Flüssigstahlströmungen ebenfalls unterschiedliche Wärmestromdichten, die auch bei einer trichterförmigen Erweiterung 11 des Kokilleneingangs auftreten. Diese unterschiedli- chen Wärmestromdichten müssen durch Kühlmaßnahmen ausgeglichen werden. Dazu ist die Dicke 6 der Kokillenbreitseitenplatte 2, die gewöhnlich im Neuzustand zwischen 20 bis 40 mm oder mehr beträgt, als übliche Normaldicke mit 100% anzusetzen. Aus diesem Grund beträgt der korrigierte Neuzustand im Bereich des Gießspiegels, wie gezeichnet, nur 80% und eine durch Nacharbei- tungen bei Verschleiß eintretende weitere Reduzierung der auf anfangs 80% verminderten Dicke 6 ist bis auf ca. 5 mm Enddicke 6a (Fig. 2) beschränkt. Außerdem kann zur weiteren Verbesserung der Kühlwirkung der Kühlmittelkanal- Querschnitt 7 im Gießspiegelbereich 5 verhältnisgleich zur Reduzierung der Dicke 6 der Kokillenbreitseitenplatte 2 vermindert werden (Fig.2). Diese Maß- nahmen sind bei allen derzeit verwendeten Bauformen einer sog. CSP- Trichterkokille und bei konventionellen Kokillenplatten anwendbar. Hier kann durch stärkeres Ausfräsen der minimierte Kühlmittelkanal-Querschnitt 7 zwischen der Heißseite und dem Kühlmittel imThe continuous casting mold 1 (FIG. 1) is formed by two Kokillen- width side plates 2 delimiting the casting cross-section 1b and small end plates 3 located at the ends, wherein a coolant 1a (such as water) under pressure through coolant channels 4 (FIGS 4) is guided. As can be seen, 5 different areas 5a and 5b of the heat flux density are formed by the influence of a dip tube 12 in Gießspiegelbereich. The heat flux density in the regions 5a is higher than in the region 5b. In addition, due to the emerging from the dip tube 12 liquid steel flows also different heat flux densities, which also occur in a funnel-shaped extension 11 of Kokilleneingangs. These different heat flux densities must be compensated by cooling measures. For this purpose, the thickness 6 of Kokillenbreitseitenplatte 2, which is usually in the new state between 20 to 40 mm or more, to be set as the usual standard thickness of 100%. For this reason, the corrected new condition in the region of the casting mirror, as shown, is only 80%, and a further reduction of the thickness 6 reduced by 80% at the beginning is a further reduction of the thickness 6, which is reduced by 80% at the beginning to 6 mm (FIG. 2) ). In addition, to further improve the cooling effect of the Kühlmittelkanal- cross section 7 in Gießspiegelbereich 5 can be reduced proportionally to reduce the thickness of 6 Kokillenbreitseitenplatte 2 (Figure 2). These measures are applicable to all currently used types of so-called CSP funnel molds and to conventional mold plates. Here can by more milling out of the minimized coolant channel cross-section 7 between the hot side and the coolant in the
Gießspiegelbereich 5 reduziert werden. Der Kühlmittelkanal-Querschnitt 7 ist zunächst nicht mehr als 80% des Neuzustands des jeweiligen Anfangs- Kühlmittelkanal-Querschnitts verringert.Gießspiegelbereich 5 can be reduced. The coolant channel cross section 7 is initially not reduced by more than 80% of the new state of the respective initial coolant channel cross section.
In Fig. 2 ist die sich ergebende Enddicke 6a der Kokillenbreitseitenplatte 2 nach einer Mehrzahl von Nacharbeitungen wegen Verschleißes, Rissen u. dgl. in der Oberfläche der Heißseite angegeben, wobei eine einzelne Nacharbeitung aus einer Kupferwerkstoff-Abtragung von 0,3 - 1 ,5 mm, maximal 3,0 mm, bestehen kann.In Fig. 2, the resulting end thickness 6a of Kokillenbreitseitenplatte 2 after a number of reworking due to wear, cracks u. Like. Specified in the surface of the hot side, wherein a single reworking of a copper material removal of 0.3 - 1, 5 mm, a maximum of 3.0 mm, may exist.
Der Kühlmittelkanal-Querschnitt 7 ist im Gießspiegelbereich 5 und bis zum Kokillenausgang 9 mittels jeweils eines auf der Kaltseite befestigten Füllstücks 10 aus normaltemperaturbeständigem Werkstoff gebildet. Das Füllstück kann zumindest zur Reduzierung des Kühlmittelkanal-Querschnitts 7 justierbar sein.The coolant channel cross section 7 is formed in the mold level region 5 and up to the mold outlet 9 by means of a respective fixed on the cold side filler 10 made of normal temperature resistant material. The filler can be at least to reduce the coolant channel cross-section 7 adjustable.
Fig. 3 zeigt eine Ausbildung der Stranggießkokille 1 für eine zweiteilige Kassettenkokille, wobei wiederum der Gießspiegelbereich 5 mit dem Bereich 5a der höheren Wärmestromdichte in Gießrichtung 13 innerhalb der trichterförmigen Erweiterung 11 dargestellt ist. Die sog. Kassettenkokille besteht im wesentlichen aus der vorstehend beschriebenen Kokillenbreitseitenplatte 2 und einer rückwärtigen Adapterplatte 14, zwischen denen der Kühlmittelkanal 4 verläuft, durch den das Kühlmittel 1a zugeführt und abgeleitet wird. Auch hier können die einzelnen Kühlmittelkanäle 4 in dem Bereich unterhalb des Gießspiegels 5 tiefer in das Material eingefräst werden. Entsprechend geformte Verdrängerkörper 15 verringern den Kühlmittelkanal-Querschnitt 7 und erhöhen in diesem Bereich die Kühlmittelgeschwindigkeit.FIG. 3 shows a design of the continuous casting mold 1 for a two-part cassette mold, again showing the mold level region 5 with the region 5 a of the higher heat flux density in the casting direction 13 within the funnel-shaped extension 11. The so-called cassette mold consists essentially of the Kokillenbreitseitenplatte 2 described above and a rear adapter plate 14, between which the coolant passage 4 extends, through which the coolant is supplied and discharged 1a. Again, the individual coolant channels 4 can be milled deeper into the material in the area below the casting mirror 5. Correspondingly shaped displacement bodies 15 reduce the coolant channel cross section 7 and increase the coolant speed in this area.
In Fig. 3 sind zumindest die Kokillenbreitseitenplatten 2 als Kassettenplatten ausgebildet, die auf der Kaltseite ausbaufähig auf gekühlten Adapterplatten 14, die nicht unbedingt aus Kupferwerkstoffen bestehen müssen, anliegen.
